Abstract
The invention provides a data interaction safety protection method based on a CPK identity authentication technology. The method is applied to user login security of a user service system (S1) and interactive protection of all service data. The user service system (S1) is used for receiving a login request transmitted by a user intelligent terminal, generating a random number a and generating a CPK identification public-private key pair of the random number a by using the CPK identity authentication technology, and downwardly transmitting to the user intelligent terminal after using the CPK identification public-private key to encrypt the CPK identification public-private key pair of the random number a. A user inputs a user login command on the intelligent terminal and transmits the user service system (S1) to recognize authenticity of a user identity after encrypting the hash value which is obtained by changing the user login command. The user service system (S1) is used for generating a random number b and transmitting to the user intelligent terminal after being encrypted if the verification is passed, otherwise, returning the data of failing login. After the user registers successfully, all service data between the user intelligent terminal and the user service system (S1) uses the random number b as a session key to perform bidirectional whole secret state service data interaction.
